Abstract
This paper introduces an object model and an interaction method for a simulated experience of pottery on a potter’s wheel. Firstly, we propose a layered cylinder model for a 3D object of the pottery on a potter’s wheel. Secondly, we set three kinds of deformation functions to form the object model from an initial state to a bowl shape: shaping the external surface, forming the inner shape (deepening the opening and widening the opening), and reducing the total height. Next, as for the interaction method between a user and the model, we prepare a simple but similar method for hand-finger operations on pottery on a potter’s wheel, in which the index finger movement takes care of the external surface and the total height, and the thumb movement makes the inner shape. Those are implemented in the three-dimensional aerial image interface (3DAII) developed in our laboratory to build a simulated experience system. We confirm the operation of the proposed object model (layered cylinder model) and the functions of the prepared interaction method (a simple but similar method to actual hand-finger operations) through a preliminary evaluation of participants. The participants were asked to make three kinds of bowl shapes (cylindrical, dome-shaped, and flat-type) and then they answered the survey (maneuverability, visibility, and satisfaction). All participants could make something like three kinds of bowl shapes in less than 30 min from their first touch.

The system and technologies described in this paper differ from conventional studies and would contribute to in the following points: (1) the simulated experience system of pottery on a potter’s wheel constructed here enables a user to interact with the 3D object image projected in the air without wearing any special device; (2) the object model is easy to understand following physical laws such as maintaining volume while undergoing large deformation; (3) the interaction method is simplified while resembling actual operations on a real object and is easy to apply to other similar systems

Summary
This paper introduces an object model and an interaction method for a simulated experience of pottery on a potter’s wheel. Through building the simulated experience system of pottery on a potter’s wheel as a case study, it would be examined whether the design concept contributes a lot to the human-system interaction in a certain practical application, along with the proposed object model (layered cylinder model) and the prepared interaction method (a simple but similar method to actual hand-finger operations). The system and technologies described in this paper differ from conventional studies and would contribute to in the following points: (1) the simulated experience system of pottery on a potter’s wheel constructed here enables a user to interact with the 3D object image projected in the air without wearing any special device; (2) the object model (layered cylinder model) is easy to understand following physical laws such as maintaining volume while undergoing large deformation; (3) the interaction method is simplified while resembling actual operations on a real object and is easy to apply to other similar systems.
